Benefits of technology

[0011]Accordingly, it is an aspect of the present invention to provide a laser irradiation apparatus, which includes a plurality of laser heads from which a laser is irradiated, can adjust arranged intervals of the laser heads, and moves freely to irradiate the laser along a shape of a subject.
[0013]Since the laser irradiation apparatus may move a plurality of laser heads suited to intervals and shapes of a plurality of frits formed on a substrate, it may melt and cure the plurality of frit for a laser irradiation time once, thereby saving a manufacturing time and eliminating requirement of additional laser irradiation device according to intervals of the frits.

Problems solved by technology

This consumes great time and cost.

Embodiment Construction

[0021]Turning now to the drawings, FIG. 1 is a perspective view showing a coalesced substrate obtained by coalescing a sealing substrate sheet with a base substrate sheet during a process of manufacturing a conventional organic light emitting display in a sheet unit. In FIG. 1, a sealant is used as a frit. As shown in FIG. 1, a coalesced substrate sheet 1 includes a base substrate sheet 10, a sealing substrate sheet 20, and frits 30. A plurality of organic light emitting diodes are formed on the base substrate sheet 10. The sealing substrate sheet 20 coalesces with the base substrate sheet 10. The frits 30 are disposed between the base substrate sheet 10 and the sealing substrate sheet 20, and seals the base substrate sheet 10 and the sealing substrate sheet 20 every organic light emitting diode.

[0022]Here, a laser irradiation apparatus is used to coalesce the frit 30 coated and sintered at the sealing substrate sheet 20 with the base substrate sheet 10. FIG. 2 is a schematic view s...

Abstract

A laser irradiation apparatus includes a plurality of laser heads from which a laser is irradiated, can adjust arranged intervals of the laser heads, and moves freely to irradiate the laser along a shape of a subject. A laser oscillator oscillates a laser. A plurality of laser heads linearly irradiate the laser oscillated by the laser oscillator. A first driving means adjusts arranged intervals of the laser heads, and moves the laser heads in an X direction. A second driving means moves the laser heads in a Y direction different from the X direction.

Description

CLAIM OF PRIORITY[0001]This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application for LASER IRRADIATION APPARATUS earlier filed in the Korean Intellectual Property Office on 8 Mar. 2006 and there duly assigned Serial No. 10-2006-0021890.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a laser irradiation apparatus, widely used for all kinds of industrial purposes, in particular, for a process of manufacturing an organic light emitting display.[0004]2. Description of the Related Art[0005]An organic light emitting diode can emit light by using an energy discharged while an excited molecule generated when a hole and an electron, which are introduced from two opposite electrodes to an organic light emitting layer, are engaged is returning to the ground state, by locating the organic light emitting layer between the two electrodes and applying voltages to the ...
